Why It Matters

A critical access control flaw in Tata Consultancy Services Cognix Recon Client v3.0 enables authenticated users to reset passwords for any user account, creating immediate risk of unauthorized access and account takeover across the organization. This vulnerability affects all systems running the vulnerable version and requires urgent remediation as no patch is currently available.

Business Impact: Severe

Compensating Controls

Implement Web Application Firewall (WAF) rules to block password reset API requests from non-administrative sources; enforce network segmentation to restrict access to Cognix Recon Client to authorized administrative users only; disable password reset functionality at the application level if operationally acceptable; enforce multi-factor authentication for all account access; increase monitoring and alerting on password reset events and failed authentication attempts; implement IP whitelisting for password reset operations.
